Thread: minor problem with detecting int64 in configure

minor problem with detecting int64 in configure

From

I have found a minor problem with current configure.in.

[AC_MSG_RESULT(yes) AC_DEFINE(HAVE_LONG_INT_64)],

this line produces something like:

  echo "$ac_t""yes" 1>&6 cat >> confdefs.h <<\EOF

and would append garbage "yes cat" to confdefs.h. Of course the result
confdefs.h is not syntactically correct therefore following tests
using confdefs.h would all fail.
To avoid the problem, we could switch the order of AC_MSG_RESULT and
AC_DEFINE (see attached patch). This happend on my LinuxPPC box.

Oops.  My bad.  Patcher please note that the HAVE_LONG_LONG_INT_64
test needs the same fix.

Done.  Autoconf done.
